This product is amazing. I have noticed real world fuel economy gains. That means less internal engine friction, and that translates into less engine wear. It more than pays for itself with the extra MPG gains. I'm very skeptical of additives. I'm always researching them, but I look for real review, real world data, people who keep spreadsheets of information, and long term trends. I always want to know that an additive works, doesn't have negative side effects, and is worth the cost. I would recommend this in any engine. If your engine holds 9 or more liters or quarts of oil then buy two.

Great Product. I use it in both my BMWs

reduces considerably the oil consumption for my A4 B7 3.2. 198 000km on the car and still make my oil changes every 10 000km without having to top off in between oil changes

I started to notice my engine running smoothly after adding this. I'm currently using the FS Liqui Moly engine oil in my Toyota 3.0L D4D. I used two (2) cans for the eight (8) liters of engine oil.

This stuff is AWESOME!!!

I run 0w20 Motul Eco-lite in my car, and while I feel great about its ester content, my car was somewhat audible, shall we say. Added this to the oil, and a couple of hundred miles down the road I noticed that my car engine approached Tesla Model S decibel levels :))) if that isn't reduced friction, I don't know what is.

The best stuff in the world to protect your cars engine and you will feel it while it is in the engine protecting it. Micro ceramic solid lubricant suspension based on hexagonal boron nitride (wow that's a mouth full). The stuff works! I have 240k on my Volvo S60 2.5T AWD and I put this in every 30K. The engine feels like it has no wear. Of course I have oil leaks it is a Volvo Turbo'd car!
